DRAWING TEMPLATE FOR DIE SETS.

Application filed February l l, 1927. SerialNo. 168,054.

This invention relates to templates or guides for use by machinedraftsmen in expedit-ing their work in making working drawings ofcomplementary die and punch parts used in plate metal manufactures, andthe present improvement has for its object:

To provide a structural formation of a transparent guide or template, bymeans of which,and afterthe completion of the plan views ofcomplementary die and punch members used in the formation of plate metalarticles, the proper size of a standard die set or holder for such dieand punch members can be readilyascertained and in like mannergraphically and accurately delineated on the aforesaid plan views in arapid manner, all as will hereinafter more fully appear. i In theaccompanying drawing Fig. l, is a face elevation of a drawing templateembodying the invention. Fig. 2, is a sectionof the same on line22Fig.1. *Like reference numerals indicate like parts in both'views.

The general practice heretofore followed a in the preparation ofassembled plan views of the complementary and coacting p arts of die andpunch mechanisms has been: with the completion of the plan views of thedie and of the punch,'to draw, on suchviews plan views of therespectiveand proper die shoe and punch holder thereof for thesubsequent use and guidance of a mechanic in the making of a completedtool or appliance. As distinguished from such mode of procedure, thepresent improvement involves, first, the use of a series of templates orguides of progressively increasing sizes, and correintended tocorrespond, and "so that. thedraftsman can't'ransfer such numerical orlike le end to the views he is making.

In t 1e preferred form offthe drawing template or guide shown in thedrawing, the same will comprise a flat plate or sheet 1 of celluloid orlike transparent material, with the border portion of the template of acounterpart outline to that of a die shoe of a standard die set, withthe purpose in.

'view of a rapid delineation otthe outline of to illustrate theinvention. The innerportion of the template 1 is in the presentimprovement formed with a series of orifices, apertures. and markings,as follows 7 At its midlength and midwidth the template 1 is formed'withlines or markings 2 and 3, intended to correspond and to register withthe center lines of the drawing of a die member and of a punch member,and in addition indicate at the intersection of said lines 2, 3, thecenter on which to draw a a circle representing the attaching shank ofthe punch holder of a standard die set.

Adjacent to the two rearward cornersoi thetemplate l are formed circularorifices 4, corresponding with the leader pins ofthe die holding shoe ofa standard die set, both as todiameter and position of the parts Andsurrounding the orifices 4, are circular markings 5 indicative of thesize andlocation of the guide bushings of the punch holder of a standarddie set. Said bushings having guiding engagementwith the leader pinsabove referred to.

In spaced and partly concentric relation to the orifices at. thetemplate 1 is formed with a rearward pair of apertures 6 of a cyma orreversed curve shape, and adjacent to its side borders the template 1 isformed with a like pair of apertures 7, of a cyma or eversed curveshape, partly in concentric relation to the aforesaid orifices 4, Thepair of apertures 6 are adapted for connection by a line or marking8,indicative of the amount and the formation of a pair of parallel lines arectangular shaped body portion of the or markings 9 indicative of theside lines of punch holder ofga standard die set. Andin addition saidpair of apertures are adapted for connection bylines or markings 10 withthe pair of apertures 11, hereinafter described, to indicate as well asaid in the formation of a pair of lines or inarhings EMERS- ponding tothe side lines of the V shaped bodyportion of the punch holder of astandard die set upon a plain view of punch memben.

The pair of apertures llabove referred to,- are ot an ohtusc angle shapeand are formed in spaced relation and equidistant from thetransverseceuter line 2-1 of the templatcrand near the forward edgethereof; Said apertures are adapted for connection by a line or marking12, to indicate the amount of material or stock of the forward portionof audio shoe to be left for strength and stabilitmand in addition toindicate and aid in the formation of a line corresponding withtheforwardedge of the punch holder of a standard die setupon the planview of the punch member.

Inpractice, atemplhte 1 of the proper size, is first selected by trialfrom a plurality'of diifer'ent'sizes of templates, after which theselected template is accurately applied in succession to the respectiveplanlviews of the die and punch, and the required marklugs made throughthe series of orifices and apertures above described, after which andwith the removal of the template, the plan views aforesaid can becompleted with ease, rapidity and. certainty.

It is intended that suitable legendary matter maybe impressed upon thetemplate, as suggestive in aiding the drattsman in th use of the presentappliance.

Having thus fully described my invention, what I claim and desire tosecure by Letters Patent, is i 1. A template for use in making; drawingsof punch and die mountings, the same comprising a plate of transparentmaterial having a border outline corresponding with the border outlineof a standard die shoe,

the plate being formed with orifices indicative of the position of theleader plus of said shoe, with a transverse guide line midway betweensaid orifices, and with a longithdinal guide line in spaced relation tosaid orifices, said lines atlording means for positioning theteniplateon a drawing, of a punch and die previous to the production on saiddrawing of the outlines of a suitable size of a die set; and itsorifices indicating the leader pins of said die set. i

A. template for use in unrking drawings of punch and die mountings, thesame comprising. a plate of transparent material havihg a border outlinecorresponding with the border outlines of a standard die shoe,

of a reverse curve shape ncar the aidepprtions of the plate in partlyconcentric relation to the aforesaid orifices in the smile,

with a pair of parallel markings extending from said secondary aperturesind-icativfi, 0f the side outlines of the punch holder of a die set, andwith transverse and longitudinal center lines. i a 1 3. i itcinplatc foruse in making drawings of punch and die mountings the same com prising:a plate of transparent material having a border outline correspondingwith the border outline of a standard die shoe, the plate being formedwith orifices indicative of the position of the leader pin of said shoe,with transverse and longitudinal center lines, with a, pair of aperturesof a reverse curve shape near the rear border of the plate and in partlyconcentric relation to the aforesaid orifices, with connecting markingsbetween said apertures, witha second pair of apertures of a reversedcurve shape near the side portions of the plate inpartly concentricrelation with the oriices aforesaid, with a pair of'obtuse angleshapeaperturesnear its forward edge,w1th pair of markings connecting thesecondary and obtuse angle apertures, indicative of the angulansidefaces of the punch holder of die set. I
